Cannot connect Bluetooth headphones in Dual Channel SBC XQ
Hello and thank you for the progress on this modern alternative to pulseaudio and jack. . I am posting this issue as a follow up on the below exchange some time ago, after trying several builds over time:
I installed pipewire on a fresh manjaro VM, as a test bed before transitioning from a forked version of pulseaudio (using pali's enhancements) from all my machines.
.
Did the required configuration (including setting bluez5.sbc-xq-support=true). My Bose 700 do connect in Joint Stereo however NOT in dual channel, not with the highest quality SBC XQ setting.
.
The same headphones are connected to the same dongle in SBC XQ Dual Channel using other software (bluez-alsa, pali's pulseaudio on manjaro, and also zenwalk) so it is not a hardware issue.
.
To help with diagnosing the problem I have just compiled the following files:
.
Attached file capabilitiesBose.txt is BTmon showing the Dual Channel capability is advertised by the headphones, and the successful SBC Dual Channel connection with other software solutions.
Attached file pwdump.txt is a pipewire dump.
Attached file journalctlentries.txt is a couple of easier to read logs (grep a2dp and grep blue).
Attached file failedDual-BTmon.txt shows the current bluetooth negotiation.
Attached file configs.txt shows the pipewire conf files.
Attached pwinfoall.txt shows the output of pw-cli.

As @pvir mentionned he can successfully use his headphones in Dual Channel mode, I am hoping this can be done as well with the Bose headphones, and would appreciate any guidance. Thank you.
